Old trading strategies don't work well in the Internet age?

Question

Is it true that some trading strategies that worked well 20 years ago now don't work, or give much less profits, due to having many people doing the same with the advent of Internet brokers?

For example Zack's and Reuters earnings estimates have lost their snap, even Julian Robertson of Tiger Management and Michael Steinhardt, suffered severe losses in the 90s. John Templeton has had reduced earnings.

Answer 1

Some trading strategies might be obsolete in this era. Strategies might not work however the habits to investment still stand.
As things get complicated, minds have to think more to mix here and there to get a good strategy.

Answer 2

I did not realize anyone suffered losses during the 90s. That was the bull market to beat all bull markets. Were they shorting stocks?

Now in the 1st 3 years of the 2000s, that would be a different story. Many suffered losses then. In fact almost everyone that wasn't short.

As for the internet. In my opionion it has increased the demand for stocks and other investments. Every time someone recommends a stock as a buy, the stock jumps 2 bucks in price. I can't help thinking that they bought into the stock before issuing the buy recommendation so as to sell it to the gullables.

Indeed the markets have changed in the last 20 years as they had also change in the previous 20 years. I remember when 5 miilion shares was a heavy day on the big board.

It does however seem to me that the tried and true trading strategies that have worked well in the past seem to also work well today. But then I am not a day trader so I may be missing a few trends here and there.
