My Best and Worst Trades

NEW YORK ( TheStreet) -- I have been trading stocks since I was 13 years old, in 1968.

The first trade was memorable. I bought $200, 10 shares, in a computer timesharing company called Datamation Services. For me, it was a very big deal.

I did it through a broker, using a custodial account, and when it got to $80/share, I said sell. Unfortunately it was a custodial account -- the broker told my parents not to sell. They didn't, and the company soon disappeared, taking my $200 with it.

I kept the certificate as a souvenir, alongside a 1921 Irish bond from my great-aunt, hand-signed by Eamonn DeValera himself. As she was fond of saying, after a few drinks, "up the rebels."

Since then I have had a great fondness for discount brokers, the kind that let me do my own thinking and initiate my own trades.

I haven't always been right, of course.

For one thing, I've managed to lose a lot of money on what's now Apple Inc. ( AAPL). I bought into it in the 1990s, while it was wobbling from one CEO to another. Soon after Steve Jobs returned, I got tired of waiting for gains and cashed in my chips, which is one reason I still work for a living.

I took another flyer on Apple last year, and naturally my timing was impeccable. I'm out about $5,000 so far. I'm certain that all Tim Cook's problems would be quickly solved if I just sold my stake. When I do, I'll let you know.

I can laugh about Apple because, by and large, my investing is profitable. I call broker Charles Schwab & Co. ( SCHW) my "bookie," and when I decide to buy something, tell friends I'm placing a "bet" with "Charlie." He takes a very modest "vig," under $10, even when I'm betting thousands, and I never have to wait for my winnings -- the teller window is always open.

My best trade ever is probably Intel ( INTC), which I picked up around the time I bought my first Apple shares. Intel doubled, split, and so I sold 100, my original stake. It doubled again, split again, and I sold 100. By the end of the decade, I had thousands of dollars in profits and 600 shares.

I've made money on IBM ( IBM) and Costco ( COST). I've broken even on General Electric ( GE), and lost a little on Red Hat ( RHT).

All this is done through a retirement account, called a SEP IRA, and so I don't think about tax implications and just go for the capital gains.

Whenever I have any stake in any investment I write about for, in that SEP IRA, it's disclosed at the bottom of the piece. You may see that I am long on Google ( GOOG). If by long, you mean I own 10 shares, then I'm pretty long. I doubt Larry Page stays awake nights worrying about me.

I am not an expert. I'm an ordinary investor, like you. When the market goes up, I make money. When the market goes down, I lose money. At one point, in 2009, my IRA was worth just $140,000, instead of the $220,000 I'd pushed into it over the years. Now I'm more than whole. Charlie says I'm ahead by $33,000, but the memory of 2009 lingers - had I panicked I might be retiring with a tin cup in my hand.

The point is, I have no special insight. I write for as a reporter. I'm not a big investor, not a banker, and certainly not a big swinging, uh, moneybags. I'm not a "player," just one of the guys in the stands, in a corner of the press box, looking for the free coffee and doughnuts.

And I have one more investment "tip," my very best trade.

Back when I was writing for ZDNet, after it became part of CBS ( CBS), I pushed all my money into mutual funds, because my employer said it was the ethical thing to do, and I feared losing my job if I didn't do the ethical thing.

One of those mutual funds tracked the S&P 500, and is run by my bookie. The Schwab S&P 500 Index ( SWPPX) is up by 16%, but compounded that's $15,000. I don't think about it, I let others think about it, and I think it's my best bet of all. Except, perhaps, for Aunt Till's bond.

Up the rebels.
