Firstly, this helpful information from Investopedia: Technical analysis and fundamental analysis are the two main schools of thought in the financial markets. As we've mentioned, technical analysis looks at the price movement of a security and uses this data to predict its future price movements. Fundamental analysis, on the other hand, looks at economic factors, known as fundamentals.
Both ways involve stock market investing and each has its own pros and cons. Now, let's answer the question head on:
Fundamental Analysis (FA) is great for people who don't have the luxury of time. This is in contrast with Technical Analysis (TA). Since FA looks at more objective factors {sustainability, growth, etc.}, people can make sense out of it rather than TA which is driven mostly by sentiments. Also, there are resources out there that suggest which stocks to buy based on their case studies {coupled with proper caveats, of course}. Good examples are Bo Sanchez's Truly Rich Club {TRC} and COL Financial's Fundamental guides.
For a 5-year time horizon, gains are pegged, at most ~40%. We want quick gains, well, who doesn't? However, we have to be realistic when dealing with stock returns. This percentage is based from 2011 to 2015's study from TRC. In short, we have to be patient and take on all the volatile movements for the time being. Take comfort by the fact that 40% is way higher than the PH inflation so in a way, we're still in a good position.
