If you really want to know which stocks the experts – and those in the know – are buying, pay attention to what they’re doing. Stock reports, company reviews, and press statements are helpful, but you’ll get significant information from watching what the insiders are up to.The insiders – the corporate officers and board members – have to disclose when they snap up shares to prevent any unfair advantages. Tracking their stock purchases can be a useful strategy because if an insider spends their own money on a stock, it could signal that they believe big gains are in store.So, investors looking for stocks that may be flying ‘under the radar,’ but with potential to climb fast, watching for insider purchases identify some sweet market plays. To make that search easier, the TipRanks Insiders’ Hot Stocks tool gets the footwork started – identifying stocks that have seen informative moves by insiders, highlighting several common strategies used by the insiders, and collecting the data all in one place.Fresh from that database, here are the details on three stocks showing ‘informative buys’ in recent days.TravelCenters of America (TA)We’ll start with a company that you probably don’t think about often, but that does provide an essential service. TravelCenters of America is the largest publicly traded owner, operator, and franchisor of full-service highway rest stops in the US. TA started out operating truck stops for rest, repair, and maintenance, and has since expanded to full-service fueling stations offering both gasoline and diesel, fast-food restaurants, convenience stores, and other rest stop amenities. Their network of rest stops is part of the infrastructure that makes long-distance motor transport, both private and commercial, possible in the USA.As can be imagined, the social lockdowns and travel restrictions during the coronavirus pandemic were not good for TA. The good news is, the worst of the pandemic hit during Q1, and the first quarter is normally TA’s slowest of the year. This year, the first quarter showed a net loss of $1.81 per share. In the second quarter, when warmer weather normally leads to increased driving, the pandemic restrictions were also – at least partially – lifted, and TA reported a sudden turnaround, with a 59 cent EPS profit. Even so, that missed the forecast by almost a dime. The outlook for Q3, normally TA’s strongest of the year, is for EPS of 73 cents.Turning to the insider trades, Adam Portnoy of the Board of Directors has the most recent informative buys. Earlier this month, he purchased over 323,000 shares, laying out more than $5.32 million for the stock. Analyst James Sullivan, of BTIG makes two observations about TravelCenters. First, he points out, “The long-haul trucking industry has an approximate 71% share of total primary tonnage in the U.S. freight industry, making it the primary mode of freight transportation.” Sullivan then adds that this opens up opportunity for TA going forward: “The increasing demands of the nation’s large trucking fleets for consolidated service providers that can provide fuel and truck service on a national basis appear likely to drive additional consolidation in the industry.”Sullivan rates TA shares a Buy, and his $34 price target suggests the stock has an impressive 82% upside potential for the coming year. (To watch Sullivan’s track record, click here)Overall, shares in TA are rated a Strong Buy from the analyst consensus, based on 5 recent reviews including 4 Buys and 1 Hold. The shares are selling for $19.24, and the $22.70 average price target implies room for 18% upside growth. (See TA stock analysis on TipRanks)Highwoods Properties (HIW)The next stock is a real estate investment trust. Highwood operates mostly in the Southeast US, but also in Pittsburgh, where it acquires, develops, leases, and manages a portfolio of suburban office and light industrial properties.Where most companies reported heavy losses during the corona crisis, HIW saw revenues in 1H20 remain stable. EPS has grown sequentially into Q1 and remained flat in Q2 at 93 cents. Both quarter beat EPS expectations.Despite the solid financial results, HIW shares have still not recovered from the market collapse of midwinter. The stock is down 27% year-to-date.Through all of this, Highwoods has maintained its dividend, as is common among REITs. The company has a 17-year history of dividend growth and reliability, and the current payment of 48 cents per common share has been stable for the past 7 quarters. At this level, it annualizes to $1.92 and gives a yield of 5.8%.Highwoods’ insider trading has come from Board member Carlos Evans, who purchased 10,000 shares for $337,000 dollars last week. His move was the first informative buy on HIW in the last 6 months.Truist analyst Michael Lewis is impressed by the quality of HIW’s portfolio. He writes, “We continue to believe that HIW’s portfolio is one of the best-positioned among traditional office REITs in light of the COVID-19 pandemic. Rent collections have been excellent and there are no large near-term lease expirations. More broadly, the portfolio should benefit from being focused in drivable, close-in Sunbelt suburbs.”In line with these comments, Lewis rates the stock a Buy. His price target, $45, indicates a 31% potential upside from current levels. (To watch Lewis’ track record, click here)Overall, HIW has a cautiously optimistic Moderate Buy consensus rating from the Street. This breaks down into 2 Buy ratings and 1 Hold. We can also see from TipRanks that the average analyst price target is $43, which implies a ~25% upside from the current share price. (See HIW stock analysis on TipRanks)VEREIT (VER)The last stock on our insider trading list is another REIT. VEREIT is major owner and manager of retail, restaurant, and commercial real estate, with a portfolio that includes over 3,800 properties worth a collective $14.7 billion. The company’s assets are 45% retail and 20% restaurants; the rest is mainly office and light industrial sites. The total leasable square footage is 88.9 million square feet.So VEREIT is a giant in the REIT sector – but size didn’t protect it from the general downturn this year. Share performance has been lackluster, and revenues have been falling off gradually since Q4 of last year. The second quarter results showed $279 million on the top line, the lowest in a year – but the quarter also saw earnings turn back upwards, reaching 17 cents per share.VER cut back on its dividend earlier this year, reducing the payment to 8 cents per share to keep it in line with earnings. That dividend has been maintained, and the next payment is set for mid-October. The current dividend yield is 4.5%, well over double the average found among S&P stocks.The big insider trade on VER comes from Board member and CEO Glenn Rufrano. He spent over $252K on a block of 40,000 shares, pushing the insider sentiment on this stock into positive territory.Covering the stock for JPMorgan, 5-star analyst Anthony Paolone sees an important strength in VER, noting that the company has been successful in collecting rents during the crisis period. “[Its] collections showed good improvement going into July, with 85% collections in 2Q and 91% in July; when considering all the abatements and deferrals, it appears that at this point about 94% of pre-COVID contractual rental revenue has been addressed, and it seems to us that a normalized run rate for this vast majority of the portfolio should take hold in early 2021; the company is making progress in working through the remaining 5-6% of non-collections,” Paolone noted.Paolone gives VER an Overweight (i.e. Buy) rating, and his $8 price target implies a 22% upside for the next 12 months. (To watch Paolone’s track record, click here)All in all, VER has drawn optimism mixed with caution when it comes to consensus opinion among sell-side analysts. Out of 5 analysts polled in the last 3 months, 3 are bullish on the stock, while 2 remain sidelined. With an 11% upside potential, the stock's consensus target price stands at $7.25.
