So far I have not much luck in the stock market, a bit of hit & miss, due to lack of inside knowledge (compared to fund managers) & time. I am thinking of putting most of my money in index funds such as Vanguard or SPDR ASX 200. Just wondering if the company goes broke, will I lost all my money. If this is the case then by putting all the money in an index fund it defects the purpose of diversification so not to put all the eggs in one basket ! Any comment please.
