my opinion....
I myself had never traded nasdaq stocks until '96. Prior to that I traded listed stocks, and options. Then I got involved in SOES trading. So it was a totally new experience.
I did fairly well. It was an easy time. Just come in an buy Iomega and Sun and Intel and Microsoft and Cisco on every dip. Hold them overnight. Easy money.
Well those days are over. Now, as has been mentioned, nasdaq traders seem to be gravitating to listed stocks more and more.
I know several very successful traders that never bothered with the series 55, and have no interest in trading otc.
Scalpers cannot (IMO) trade OTC in short time frames due in large part to decimalization. And also volatility. Watch Microsoft and tell me how you can possibly trade that stock for an eight. Can't be done. Less expensive otc stocks can eat you alive with commissions..
But there is no reason not to trade nasdaq stocks with a different approach. Tech stocks are probably the most trending of all sectors. When playing trends, it is hard for me to imagine doing it seriously without trading otc stocks. So it all depends on style.
What are you trying to accomplish? What is the best instrument to use to achieve your goals?
Again, this is just my opinion. But for me, on certain days I am more comfortable trading listed stocks very selectively. And in short time frames (scalping). On other days, I want to build positions in a sector. If that sector happens to be technology, I will feel that I am missing out if I don't include otc stocks. Also, they are much easier to exit early if held overnight for a gap opening. I have so often sat with a listed tech stock like LSI or ADI early in the day to see ridiculous spreads, little volume, and specialists that give me a persecution complex (but that's just because they are persecuting me).
So as I always have maintained, comfort is crucial in trading. If you are more comfortable with listed, fine. If otc, fine. If you can trade both, fine again.
If you can make money, you are doing the right thing. If not, make adjustments. If listed vs. otc is a consideration, make an evaluation of which treats you better. There are no rights or wrongs about this issue. Just preference and comfort and rate of success.
Happy trading to all,
