I think we are combining two distinct issues. One is stock picking/ideas related to age. I don't see anyone arguing that stock picking/ideas/good thought-through posts/etc. are a function of age (assuming one is at least old enough to read/write). The 15 year-old can be assumed to be indistinguishable from the 50-year old. And wisdom and perspective don't necessarily enter in to it.
But if anyone "doubts there is such a thing as grizzled veteran's wisdom and perspective" regarding making money in the stock market, I will argue with that. There's a heck of a lot more to the process, as we know, than just identifying good stocks. Like knowing when to hold, being able to hold, when to add, when to sell, understanding our own risk tolerance (which means being aware of our own personality), understanding the purchase in terms of the overall portfolio (not just as a stock out there by itself). In this market, with 15-year old kids having newsletters and national followings, and maybe even good performance records (why not? Everything seems to be blooming now.), it just isn't easy to see. But for anyone with 8-12 years buying and selling stocks - imo, they will have have a veteran's perspective which is quite different from someone with ony three years' experience (whether that three years is from a 15-year old or from a 50-year old). |
