I think this explains a lot. No one has their age on their avatar of course, but the most dedicated equities fans I see online tend to be in the 25-35 age group. I'm not that much older but I've seen two large stock market corrections in my adult life, including one where trusted corporate Irish names became worth actually nothing or close to it over the course of 18 months. I'm allergic to holding any specific stock in concentration and I am relaxed about equity performance only over a period of two decades or more.
Personally I've made close to half a million of a paper gain in property, some of which I could sell up and walk away from. Given that this was leveraged I've increased my equity by a factor of ten in less than a decade. So I can see the upside to property but (given my age) I still have close friends still nowhere near what they paid in 2006 for their apartment.
A lot of this does indeed come down to personal risk tolerance but what I see (and this is anecdotal) is an underestimation of equity risk by posters in this 25-35 age group.
In the equation there are so many things that are much more certain than equity returns. The tax regime isn't going to change radically, interest rates can only go up a few hundred basis points, inflation will not be in double digits, and you have have a reasonable idea of your own earning prospects. Equities can and do rise and fall by 30% in a 12-month period, and have seen nominal declines over a decade-long period.
I don't want to call an equity market overpricing (I've been wrong before) but mechanically the longer you are from the last bear market the closer you are to the next one. If you have no adult memory of this you are going to get a nasty surprise.
