The line graph displays the stock values of four different high-tech corporations from 2011 to 2016.
Overall, Facebook’s value steadily increased, while Yahoo’s decreased. Apple’s stock price fluctuated wildly throughout the period and Google’s stayed relatively unchanged.
Facebook started the period with a stock market valuation of approximately 7,500 and this consistently moved up in value year on year to reach a peak of around 20,000 in 2016. Yahoo began the recorded period with a very similar value to Facebook, but in contrast, its stock devalued every year, until it reached a low of about 2,500 in 2016.
Apple stock was valued at just below 5,000 in 2011 and this jumped dramatically to nearly 35,000 the following year, before plummeting to around 7,000 in 2013. It recovered slightly in 2014 to around 12,000 and subsequently fell to a price of just over 5,000 in 2016. Google’s shares remained at around 1,000 for the entire period.
