Avoid sideways market. Ride exponential and trending market. Find opportunities when trend is about to change. Get into the market at the beginning of the trend. Ride it all the way up until the trend changes. Take some profit off. Rotate capital from Large Cap to Mid Cap to Small Cap.
Repeat.
Don't fall in love with any asset or stocks or names or whatever. Follow the big money/smart money.
Extra: Learn programming. Learn how to scrape for data and historical data. Understand "theme". Understand "cluster". Understand how smart money operates. Stocks/Assets always move in unison and together. Identify names that belongs to the same category. Adjust your risk accordingly. Small cap have more upside but also more risk. Small cap is only suitable during a bull market when the moves have been made by the Large cap. Always take some money off the table. Don't risk everything. Have a screener to identify new names that is breaking out/breaking out all time high. Cluster all the names to their respective categories. Always constantly looking up for opportunities. Only computer can do this 24/7.
