But let’s use a couple of examples:
– trading: I buy a basket of stocks this morning with the intention of reselling before the close
– investing: I build a portfolio of stocks with the intention to keep it a relatively long time, because I think that these stocks value will increase due to whatever reason, growth, value, the economy…
I also like the following classification, which I believe comes from Minsky:
– Profits on the position neither depend on price variation of the asset, nor on cost of carry: I am investing.
– Profits do not depend on price variation, but only on positive carry: I am trading.
– Profit depend on price variation of the asset: I am speculating.
The example and the definition are not equivalent, but they give a rough idea of what trading is and what investing is. The border between both activities can be blurry. But if you invest, you do not need a market. You can buy a bond with the intention of holding it to maturity. If you trade, you need a market to close the trades.
