Oct 1999 -- IDCC was the stock. QCOM was blowing up and making headlines and heads turn like crazy. $1000/share target throw out by a goofy analyst. I went looking for a competitor and found IDCC (was IDC on the AMEX then). I believe it was $4-6/share, profitable, debt-free, and the only major competitor to QCOM at the time. IDCC jumped up to $10/share. From there it started getting a lot of attention from the QCOM players looking for the next one and IDCC found itself around $25/share by the end of 1999. Friends, family, everybody was telling me to take my profits. I was in bubble hype mind and thought it was going to $200/share, lol.
So I go on vacation for New Year's shortly after Xmas. Zero laptop at the time nor internet access. I get a phone call being told the CEO of IDCC got on CNBC, did an interview, and when asked about how much profit he expects IDCC to make, he said "You're going to need a calculator with a lot of zero's" -- IDCC went to $50 I believe that day. Next day cracked $80/share. I was rich!! (to me....was all in but didn't have much money to my name back then) lol....was all in on margin at the time. I think I ended up selling at $45/share on the way down giving back mucho profit.
I played IDCC several other times sometimes with mild success, sometimes with mild losses. Only other time that gave me large profits was at the end of 2000 I got my monthly magazine "Individual Investor" delivered that subscribers would get a full 2 weeks before it hit the shelves. In there were 3 articles pumping IDCC, one of them called it "a sleeping giant" which I agreed with at the time. IDCC was back to $4 a share....I loaded up on margin anticipating when the articles hit the shelves the stock will explode, and it did. Ran to $14/share. I got out around $10/share I believe.
