The investing environment is affected by inflation, war and a pandemic.

Financial clarity and strategy are in demand, as shown by the thousands of shareholders who met April 30 in Omaha, Nebraska, for their annual conference or watched the live stream on CNBC.

One of the richest men in the world, Warren Buffet, is a 91-year-old investor and business legend known for his strategic financial advice and prowess. What you can learn from him is about inflation, index funds and value investing.

1. Inflation is out of investors’ control

Inflation is a problem for investors, according to Buffett on April 30. The rising prices of goods and services means the U.S. dollar can't buy as much as it used to.

Families in the U.S. are already dealing with decades of wage stagnation and are now facing rising food, gas and shelter prices. It is wise for consumers to focus on what they can control, because market changes and global events are out of an individual investor's sphere of influence. Investing over the long term is the best way to beat inflation, and in most cases, that means staying the course with your investing strategy.

Warren Buffet's investing prowess will go on forever after researchers cracked his investing code.

2. Index funds can provide simple, effective diversification

For most people, the best thing to do is own the S&P 500.

You can buy a diversified slice of a market or industry with low-cost index funds. It spreads out the risk of your investments, which is important during volatile times.

Stock picking, or actively managing a financial portfolio by buying individual stocks, can be expensive, time-consuming and risky. Most professional money managers can't consistently beat the market. They might have a few good years, but 70% to 80% of fund managers will not do well in the stock market.

The data shows that 80% of actively managed funds underperformed the S&P 500 in 2021.

When asked about stock picking on April 30, Buffett and Charlie Munger didn't know what the stock market was going to do. I don't think we've ever made a decision where either of us has said or thought we should sell based on what the market is doing. Or, on what the economy is going to do. We don't know.

If you want to get started with index funds, you need to pick an index like the S&P 500 or the Wilshire 5000. Many investors choose index funds by their expense ratio or annual fee. When you are ready to buy, you can do it through an investment account. Access to index funds may be offered by employer-sponsored retirement plans.

3. Value investing can be a solid strategy

Buying into a company because you want to own it, not because you want the stock to go up, is what Warren Buffet told Forbes magazine in 1974. One strategy for choosing where and when to invest is assessing a company's value.

Value investing means buying high-quality stocks and holding them for a long time.

Investing in line with your values involves considering your social, faith, environmental or moral beliefs.

By following both strategies, he has done well for himself. At this year's annual conference, Buffett announced that his company had purchased 15 million shares of the gaming company. The acquisition is one of the recent examples of the strategy of picking cheap investments instead of high growth stocks.

Insurance, Apple, railroads and energy are the four main areas in which Warren Buffet prioritized his beliefs. The railroads are an indispensable asset for America as well as for the company, according to the letter.

Warren Buffet and his company are once again performing better than the stock market. Apple is one of the reasons.

Investing based on your values is still an important consideration even for those with a small amount of money. Let's focus on what you need to do. He says to look at how we can do that through a particular lens.

If you're interested in value investing, you'll need to research underpriced and overlooked companies in the stock market, which is easier when the market is down.
