In trading on Tuesday, shares of Marathon Petroleum Corp. (MPC - Get Report) touched a new 52-week low of $40.45/share. That's a $67.87 share price drop, or -62.66% decline from the 52-week high of $108.32 set back on 02/26/2015. Large percentage drops always require that the stock post even larger percentage gains from the low in order to recover the old price point, and for MPC that means the stock would have to gain 167.79% to get back to the 52-week high. For a move like that, Marathon Petroleum Corp. would need fundamental strength at the business level.

Here's a rhetorical question: Who knows more about fundamentals at the business level than the company's own insiders? So let's take a look to see whether any company insiders were taking the other side of the trade as MPC shares were being sold down to this new 52-week low, focusing on the most recent trailing six month period. As summarized by the table below, MPC has seen 3 different instances of insiders buying over the past six months.

Purchased Insider Title Shares Price/Share Value
08/20/2015 Timothy T. Griffith Sr. Vice President and CFO 1,000 $54.11 $54,110.00
08/20/2015 James E. Rohr Director 2,400 $53.40 $128,159.52
09/03/2015 John J. Quaid Vice President and Controller 400 $47.15 $18,858.40

In the short run, while the new 52-week low suggests the stock is at the cheapest price and perhaps therefore the best bargain it has been over the last 52 weeks, the low print also means anyone who has purchased the stock over that timeframe is staring at an unrealized loss. Oftentimes, that factor drives a stock's technical analysis metrics by creating overhead resistance, with investors who bought higher now anxious to reverse their trade once they are back to breakeven. The chart below shows where MPC has traded over the past year, with the 50-day and 200-day moving averages included.
