Understanding Tesla Stock Performance
Tesla, Inc. (NASDAQ: TSLA) has been one of the most remarkable growth stories in stock market history. Founded by Martin Eberhard and Marc Tarpenning in 2003, and led by CEO Elon Musk, Tesla went public on June 29, 2010, at a split-adjusted price of around $1.13 per share. Since then, the stock has delivered extraordinary returns, making it one of the most valuable companies in the world by market capitalization.
Tesla's stock performance has been driven by several key factors: rapid growth in electric vehicle deliveries, expansion of manufacturing capacity with Gigafactories worldwide, breakthroughs in battery technology, the growing energy storage and solar business, and advancements in autonomous driving technology. The company's inclusion in the S&P 500 index in December 2020 was another major catalyst for the stock.
Tesla has executed two stock splits during its public trading history: a 5-for-1 split on August 31, 2020, and a 3-for-1 split on August 25, 2022. This calculator accounts for both splits through split-adjusted pricing, ensuring accurate return calculations regardless of the time period you select. When evaluating Tesla stock returns, it is important to consider both the total return and the annualized return (CAGR), which normalizes performance across different holding periods and allows comparison against benchmarks like the S&P 500 or other growth stocks.
