I canāt comment on gambling or forex as I donāt understand the terrain, however thereās opportunity for everyone to make a killing in the stock market by doing basic things.
Invest in companies/industry you understand very well, an average person would have worked for at least 3 or more companies/industries throughout their life span ā thatās a wealth of knowledge that most of these desktop analysts havenāt got a clue.
Personally am not a fan of index investing as most are market cap weighted, the idea that Ā£1 invested in a world index ā 60% of that goes to the US mostly the mega caps doesnāt sit right with me.
