Further weakness as Selecta Biosciences (NASDAQ:SELB) drops 17% this week, taking five-year losses to 85%

We're definitely into long term investing, but some companies are simply bad investments over any time frame. We really hate to see fellow investors lose their hard-earned money. Anyone who held Selecta Biosciences, Inc. (NASDAQ:SELB) for five years would be nursing their metaphorical wounds since the share price dropped 85% in that time. We also note that the stock has performed poorly over the last year, with the share price down 42%. Furthermore, it's down 19% in about a quarter. That's not much fun for holders. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

If the past week is anything to go by, investor sentiment for Selecta Biosciences isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

Given that Selecta Biosciences didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

Over five years, Selecta Biosciences grew its revenue at 60% per year. That's better than most loss-making companies. So it's not at all clear to us why the share price sunk 13% throughout that time. You'd have to assume the market is worried that profits won't come soon enough. We'd recommend carefully checking for indications of future growth - and balance sheet threats - before considering a purchase.

A Different Perspective

Selecta Biosciences shareholders are down 42% for the year, but the market itself is up 10%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 13% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
