The most basic reason is that it gives a true comparison of the value attributed by the stock market to a given company's stock.  Many beginning investors look at one stock trading at $10 and another trading at $20 and mistakenly think the latter company is worth twice as much — that of course is a completely meaningless comparison without knowing how many shares of each company exist.  But comparing market capitalization (factoring in those share counts) creates a true &#34;apples-to-apples&#34; comparison of the value of two stocks.  In the case of HP Inc (Symbol: HPQ), the market cap is now $17.33 billion, versus PTC Inc (Symbol: PTC) at $16.96 billion.   </p><p>Below is a chart of HP Inc versus PTC Inc plotting their respective size rank within the S&amp;P 500 over time (HPQ plotted in blue; PTC plotted in green):  <img height="340" src="https://imageproxy.pbkrs.com/https://secure.tickertech.com/pics/2026/671652969A1.gif?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="600" original-src="https://imageproxy.pbkrs.com/https://secure.tickertech.com/pics/2026/671652969A1.gif"/> </p><p>Below is a three month price history chart comparing the stock performance of HPQ vs. PTC:   </p><p><img src="https://imageproxy.pbkrs.com/https://secure.tickertech.com/pics/2026/671652969A2.gif?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="600" height="340" original-src="https://imageproxy.pbkrs.com/https://secure.tickertech.com/pics/2026/671652969A2.gif"/> </p><p>Another reason market capitalization is important is where it places a company in terms of its size tier in relation to peers — much like the way a mid-size sedan is typically compared to other mid-size sedans (and not SUV's).  This can have a direct impact on which mutual funds and ETFs are willing to own the stock.  For instance, a mutual fund that is focused solely on Large Cap stocks may for example only be interested in those companies sized $10 billion or larger.  Another illustrative example is the S&amp;P MidCap index which essentially takes the S&amp;P 500 index and &#34;tosses out&#34; the biggest 100 companies so as to focus solely on the 400 smaller &#34;up-and-comers&#34; (which in the right environment can outperform their larger rivals).  So a company's market cap, especially in relation to other companies, carries great importance, and for this reason we at The Online Investor find value to putting together these rankings daily.   </p><p>Examine the full HPQ market cap history vs. the full PTC market cap history.   </p><p>At the closing bell, HPQ is up about 2.9%, while PTC is up about 0.1% on the day Thursday.  </p><p> <img height="16" src="https://imageproxy.pbkrs.com/https://www.dividendchannel.com/nslideshow.gif?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="16" original-src="https://imageproxy.pbkrs.com/https://www.dividendchannel.com/nslideshow.gif"/> The 20 Largest U.S. Companies By Market Capitalization » </p> <h5>Also see:</h5><p>   Cheap Materials Shares<br/>   CORI Price Target<br/>   Preferred Stock Ex-Dividend Calendar</p><p>The views and opinions expressed herein are the views and opinions of the author and do not necessarily reflect those of Nasdaq, Inc.</p> </div></div>
