Re: "Do you mostly concentrate on OTC bb and pink sheets?"
AAA, No, although I concentrate on OTC:BB, I do not discriminate, except that I only rarely go into pinkies. I also buy larger caps that are sitting at or near the bottom, after eliminating the risky ones (see my posts on ONEI BB this week, where I almost made the mistake of buying it @ 0.2, but fortunately decided not to). After the just release BK news, it reached 0.01 this morning, and now goes through a dead cat bounce move (you'll always find some people that still hope that what theuy read somehow is not true - to their defence, it's indeed hard to imagine that a company dating since 1880, that survived the great depression, will just declare Chapter 11, but as I wrote on that board, they do not realize that the banks force them do it, and the banks have allways the last world: screw the shareholders!) Bought last week very near to what I believe was the botton (@ 8.37 average) ICO, a very attempting long-term Energy (coal) company that will have the 10-Q on March 16.
I usually buy the large caps for long-term (e.g. NT @ 0.52 average several years back, MOT @ low 6's, NXTL in 3's). Bad choices: ARCH (now ARCHQ), after the BK still have (as a good reminder) some 360K worthless shares in my book (for over 3 years I believe) as the SOB's not even bothered to remove them for free, and won't answer any mail inquiries (Luckilly, I only got into it in the low pennies).
By far the best results, however, and lowest risk investments over the last several years (since I applied the low P/S, quality companies) I made with hand picked OTC:BB's. IGAI seem to be such a good choice.
