One thing I would like to add, these days actively managed Mutual Funds are really a waste of money. ETFs (and there are actively managed ETFs) are a much better route overall for investing in to stock or bond funds.
Another type of fund to mention would be CIT's, Collateral Investment Trust funds. These have become quite popular in todays world for retirement plans such as 401k's / 457b's / 403b's etc. They tend to be the lowest cost funds there are, but the negative is they are not regulated by the SEC, but the states comp troller, and there is a level of lack of transparency that I'm not fond of.
You seem to not understand the stock markets at all. Any company who issues stock has a highly vested interest in making you money, as so will they (they control the most shares),. Same thing goes for stock or bond funds. It’s advantageous to issuer and buyer to do well. The stock market equities are backed by tangible goods, services, real world businesses etc.
Gold is not an investment , it’s a hedge that sure, can end up being a good investment. Upside potential is not really there for gold though. Not atm.. Also you seem to not be aware of how corrupt and manipulated the precious metals space “markets”, market makers, miners etc] are.
“it is safe for every person and if a person has a small amount of investment,he should invest his money in gold and should invest in gold biscuits”.
You don’t know what you’re talking about.
