# Buy and Sell Stock Interview Problem | JavaScript Algorithms

Javascript Array Algorithms Practice:

You are given an array of integers which represent the price of a stock on a given day.
You want to MAXIMIZE your profit by choosing a single day to buy one stock
and choosing a DIFFERENT day in the future to sell that stock.

Return the MAXIMUM PROFIT you can achieve from this selling transaction.

In this video I’m going to show you the different approaches to tackle this problem, starting with a basic brute force approach, then switching something a bit more optimized using some intuition that we gather from some visuals.

## 5 Top Dividend Stocks to Buy in 2021 (Up to 8.5% Dividend!)

In this video, I’m going over 5 top dividend stocks to buy now that pay up to 8.5% dividend yield! I am a big fan of dividend investing for passive income - some of these stocks are a litter riskier, and some are definitely on the safer side.
By the end of this video, you’ll have a solid understanding of these 5 companies and whether or not you may want to invest in them. I’ll take you through their financials, stock prices and statistics, dividend yield history, and current news. Dividend stocks are an effective way to invest long term with steady passive income paid to you quarterly.

I suggest taking these dividend payments and re-investing them into your portfolio - you have the option with any brokerage to automatically do this.

Note - I have an interest in these companies. My recommendations are just a suggestion to do further research- I encourage you to do your own research about each company and make a decision for yourself, whether or not you want to invest in that particular company. This video should not be considered financial advice, and I am not a financial advisor. Do NOT buy a stock just because it was on this video. This video is just my own analysis of 5 companies and the current news surrounding them.

Also - if you want a more technical analysis, there are other channels that will dive deep into the numbers :)

## The 6 TOP Stocks To Buy in January 2021 (High Growth)

In this video, I’m going through 6 TOP stocks to buy in January 2021. These are the best stocks to buy now! Open up a Wealthfront investment account today through my link and get your first \$5,000 managed for free: http://invest.wealthfront.com/charlie

A few of these are definitely on the speculative side, being potential super high growth stocks that are extremely volatile. I was feeling a bit more risky this month! And some of them are better for long term investing that should make you a healthy profit over the next decade or more.

Make sure to watch the full video to get an analysis of each company and what they have to offer! You’ll have a better understanding of each company, which is crucial before deciding to invest. I always tell people who are getting into investing, short term any great stock can fall. But in the long term, a great stock is sure to go up.

So, I’ve done the research and I’ll share with you my findings, analysis, and opinions on each company. In this video, I go over a wide range of companies ranging from AI/Big Data, to financial tech, to plant based food, to membership stores. Some are growth stocks, and some aren’t as “momentum” based. These are the stocks to buy now in January 2021.

Note - I have an interest in these companies. My recommendations are just a suggestion to do further research- I encourage you to do your own research about each company and make a decision for yourself, whether or not you want to invest in that particular company. This video should not be considered financial advice. Do NOT buy a stock just because it was on this video. This video is just my own analysis of 6 companies and the current news surrounding them.

Also - if you want a more technical analysis, there are other channels that will dive deep into the numbers :) I like to talk about the news and where the company lies in the industry.

Happy stock buying! Please be careful because to be honest, the stock market is in an interesting place due to the influx of new traders, and we never know what will happen in the short term. Short term investing is always more dangerous, and it is entirely possible that prices fall in the short term. But in the long term, I know these stocks should perform extremely well.

## The 6 TOP Stocks To Buy in March 2021 (High Growth)

In this video, I’m going through 6 TOP stocks to buy in March 2021.
This list of stocks has a mixture of both momentum based and value-driven companies, but my analysis shows these stocks should perform well over the long term. The more speculative picks are volatile but could result in very high gains, and the safer ones should make you a healthy profit over the next decade or longer.

Make sure to watch the full video to get an analysis of each company and what they have to offer! You’ll have a better understanding of each company, which is crucial before deciding to invest. I always tell people who are getting into investing, short term any great stock can fall. But in the long term, a great stock is sure to go up.

So, I’ve done the research and I’ll share with you my findings, analysis, and opinions on each company. In this video, I go over a wide range of companies ranging from online gaming and cloud computing, to financial tech, to consumer technology, to financial services. Some are growth stocks, and some aren’t as “momentum” based. These are the stocks to buy now in March 2021.

Also, check out GE, Microsoft, Uber, Crowdstrike, Nio, Regeneron, Palantir, and Tesla if you want to do some research on other stocks not included in this list.

Note - I have an interest in these companies. My recommendations are just a suggestion to do further research- I encourage you to do your own research about each company and make a decision for yourself, whether or not you want to invest in that particular company. This video should not be considered financial advice. Do NOT buy a stock just because it was on this video. This video is just my own analysis of 6 companies and the current news surrounding them. You must do your own research before considering investing in a company (I recommend 1 hour minimum research per company). Always invest with a long term vision and try not to look at the short term.

Also - if you want a more technical analysis, there are other channels that will dive deep into the numbers :) I like to talk about the news and where the company lies in the industry.

Happy stock buying! Please be careful because to be honest, the stock market is in an interesting place due to the influx of new traders, and we never know what will happen in the short term. Valuations are all up, fundamentals aren’t looked at as much, and a lot of stock prices have future expectations built in. Short term investing is always more dangerous, and it is entirely possible that prices fall in the short term. But in the long term, I know these stocks should perform extremely well.
