Question 1

What is insider trading at MARKWEST ENERGY PARTNERS L P?

Accepted Answer

Insider trading at MARKWEST ENERGY PARTNERS L P (MWE) refers to stock transactions executed by corporate insiders—officers, directors, and shareholders owning more than 10% of the company. These individuals have access to material non-public information and must report all trades to the SEC via Form 4 filings within two business days. Over the past 90 days, 29 insiders have filed 580 transactions totaling $52.2M in trading activity. The most active insider during this period is Frank M. Semple (Executive), contributing $42.3M across 48 transactions. Monitoring these filings helps investors gauge executive confidence and potential price catalysts.

Question 2

Are MARKWEST ENERGY PARTNERS L P insiders buying or selling stock?

Accepted Answer

MARKWEST ENERGY PARTNERS L P insiders are currently net sellers of MWE stock, showing bearish sentiment over the past 90 days. Total sales of $48.5M outpace purchases of $3.7M, creating a net outflow of $44.8M. This discretionary selling activity warrants attention, though it may reflect personal financial needs rather than company-specific concerns.

Question 3

Who are the biggest MWE insiders by trading activity?

Accepted Answer

MARKWEST ENERGY PARTNERS L P has 29 active insiders who have filed SEC Form 4 transactions in the past 90 days. Frank M. Semple (Executive) leads with 48 transactions totaling $42.3M. Randy S. Nickerson (Executive) follows with 81 transactions worth $25.0M. These executives' trading patterns can provide valuable signals about company direction—particularly open-market purchases, which require insiders to invest their own capital.

Question 4

What does MWE's Alignment Score of 7 mean?

Accepted Answer

The Insider Alignment Score measures the ratio of buying to selling activity on a 0-100 scale. MARKWEST ENERGY PARTNERS L P's current score of 7/100 indicates bearish insider sentiment. Scores below 40 indicate selling pressure exceeds buying. While this can signal caution, insider selling often reflects diversification needs, tax optimization via 10b5-1 plans, or estate planning—not necessarily negative company outlook.

Question 5

When was the last insider transaction at MARKWEST ENERGY PARTNERS L P?

Accepted Answer

The most recent insider transaction at MARKWEST ENERGY PARTNERS L P occurred on Dec 4, 2015, when Corwin Bromley C. (Executive) disposed of 64,309 shares at $38.83 per share for a total value of $2.5M. This appears to be a discretionary trade, potentially carrying more informational value.

Question 6

Is MWE insider trading bullish or bearish right now?

Accepted Answer

Based on SEC Form 4 filings from the past 90 days, MWE insider trading sentiment is currently bearish with an Alignment Score of 7/100. The negative net flow of $44.8M shows more selling than buying. However, context is critical: 0% of recent transactions are 10b5-1 scheduled trades, which are pre-planned and don't reflect real-time sentiment. Focus on discretionary trades for actionable signals.

Question 7

What is a Form 4 filing and why does it matter for MWE?

Accepted Answer

SEC Form 4 is the primary disclosure mechanism for insider trading at publicly traded companies like MARKWEST ENERGY PARTNERS L P. Corporate insiders must file this form within two business days of any transaction in company stock, making it one of the most timely sources of executive sentiment. Each filing reveals the insider's identity, role, transaction type (buy/sell/grant/exercise), shares traded, and price. At MWE, we track all Form 4 filings—currently showing 580 transactions from 29 insiders over 90 days. Open-market purchases (code "P") are particularly significant because they require executives to invest personal capital, demonstrating genuine conviction in the stock's prospects.

Question 8

What is a 10b5-1 trading plan at MARKWEST ENERGY PARTNERS L P?

Accepted Answer

A 10b5-1 plan is an SEC-approved arrangement that allows MARKWEST ENERGY PARTNERS L P executives to pre-schedule stock sales when they don't possess material non-public information. These plans specify future trade dates, prices, and share amounts, providing legal protection against insider trading allegations. At MWE, approximately 0% of recent transactions are flagged as 10b5-1 trades. Most trading activity at MWE appears discretionary, meaning executives are making active decisions rather than following pre-set schedules. This can make insider signals more meaningful for analysis.
