No need to debate this, we all have been hit with the pros and cons many times. But just wanted to show an example of one that so far, has worked fine. Oncoset, which on May 15 had been trading at .23, split 1/20, so the stock price was then adjusted to $4.60. The above chart shows what it's done. The split was done for the purpose of getting to the NAS.

While I do own 1/20th of the shares I used to own (okay, that does suck a bit, but only visually and psychologically, logically, it sucks not one bit), I really don't have that much invested in this company and I certainly do not make any recommendation re same, in fact, I don't have much of a clue why it went up a lot today (but I do know that many times stocks that go up like that, go down like that, too). But, since I do follow it, I thought it might be illustrative and/or of some interest.
