splits offer no dilution. Just a number of shares outstanding changes, but everyone has the same % ownership. The 3 for 2 split is a GREAT way to open up more float, keep the price affordable for more investors, add a spotlight to the growth of the company with this positive psychology.
Not sure I understand the affordability argument. If you invest $300 it doesn't really matter if you have 20 shares or 30 shares - it still has the same value. I'd understand if using BRK-A as an example at over $100,000/share, but this is a $15 stock going down to $10 post-split. If you can't scrape together $15, you probably have more to worry about than investing in stocks.
