these big organisations has professional who analyze the market. we also can find what are the favourite stocks they prefer, each sell and purchase can tell us some information of market and how they react to the changes. so I personally feel it is a reference to me, I can learn something from it.

I learn that those expensive stocks they are quite strong such as Microsoft Apple, they are worth to buy. those penny stocks, they may have potential in future, but to me, I want to see profit now, so I will choose those blue chip stocks.

I think this is a chance. some of the crypto currency is quite expensive, let's say bitcoin, the most powerful one, u are hardly to buy one coin. But if you invest in this coin ETF, which tracks the performance of coin, you will be profited once the coin price go up.
