Hello Scataphagos,
Yes, we have to wait until the stock drop below 52 week low and get in. This is what I do for stock buying only.
As Warren said so clearly, Buy good companies at good prices.
Good Prices = below 52 week low
Good Companies = everyone should already know what are good companies.
Dump all the money in and sell once prices gets to 52 week high. This is how we get rich.
In a bear market, "52-wk low" doesn't mean much on the way down... until the final one.
