Perhaps the price variability is not a big deal, but the volatility of companies can be. A company going broke can do a lot of damage to your share portfolio- although that is not reflected in the price index.
it can be mitigated if you have the knowledge ...last count there are 2150 listed business on the ASX ... out of those 2150 In my opinion, and my opinion alone about 10% are worth investing into...
out of those 10%, you can refine it further and take out the best 30-50 stocks
you be patient and you buy them when they are cheap... you dont have to buy all 30-50 you buy as each one face its bad cycle or mishap and turn cheap...
With shares you dont need to get 10 out of ten right in fact you only need 7 out of ten to perform well and the other three either goes bankrupt or going backward you still doing well...
out of those 7 some would have double, gone up 50%, 20%, 10x, etc...
stock market best buy when there is large margin call taken place, mega headlines of 20bn or some crazy number got wiped in the market today or some crisis is playing out...
that keep out the un-educated and the mass, so there are plenty of seller but no buyer...smart buyer come in grab incredible bargains...sit back a few years
and watch his investment double along with the juicy dividend...
while he sit back, there will be plenty of guru and commentators doing the media circuit, buy and hold don't work, market so volatile its dangerous to buy,
and they do some story on some mugg who lost it all, it now becomes self fulling no one dare to venture into the market and market bottom the last of the bargain to be found..
fast forward 5-10 years, your stock double, triple gone up 10-20 times
the crowd is back, the superfund report record profit, the mass is back bid up demands it becomes a seller market and the setup for the next crash is gathering momentum....
