Question 1

What is insider trading at ZS Pharma, Inc.?

Accepted Answer

Insider trading at ZS Pharma, Inc. (ZSPH) 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, 21 insiders have filed 59 transactions totaling $58.9M in trading activity. The most active insider during this period is Marc Ostro (Executive), contributing $235.8M across 7 transactions. Monitoring these filings helps investors gauge executive confidence and potential price catalysts.

Question 2

Are ZS Pharma, Inc. insiders buying or selling stock?

Accepted Answer

ZS Pharma, Inc. insiders are currently net sellers of ZSPH stock, showing bearish sentiment over the past 90 days. Total sales of $41.0M outpace purchases of $17.9M, creating a net outflow of $23.1M. This discretionary selling activity warrants attention, though it may reflect personal financial needs rather than company-specific concerns.

Question 3

Who are the biggest ZSPH insiders by trading activity?

Accepted Answer

ZS Pharma, Inc. has 21 active insiders who have filed SEC Form 4 transactions in the past 90 days. Marc Ostro (Executive) leads with 7 transactions totaling $235.8M. Park Bioventures Lp Devon (Executive) follows with 2 transactions worth $232.8M. 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 ZSPH's Alignment Score of 30 mean?

Accepted Answer

The Insider Alignment Score measures the ratio of buying to selling activity on a 0-100 scale. ZS Pharma, Inc.'s current score of 30/100 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 ZS Pharma, Inc.?

Accepted Answer

The most recent insider transaction at ZS Pharma, Inc. occurred on Dec 17, 2015, when Alexander Robert (Executive) disposed of 30,750 shares at $90.00 per share for a total value of $2.8M. This appears to be a discretionary trade, potentially carrying more informational value.

Question 6

Is ZSPH insider trading bullish or bearish right now?

Accepted Answer

Based on SEC Form 4 filings from the past 90 days, ZSPH insider trading sentiment is currently bearish with an Alignment Score of 30/100. The negative net flow of $23.1M 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 ZSPH?

Accepted Answer

SEC Form 4 is the primary disclosure mechanism for insider trading at publicly traded companies like ZS Pharma, Inc.. 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 ZSPH, we track all Form 4 filings—currently showing 59 transactions from 21 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 ZS Pharma, Inc.?

Accepted Answer

A 10b5-1 plan is an SEC-approved arrangement that allows ZS Pharma, Inc. 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 ZSPH, approximately 0% of recent transactions are flagged as 10b5-1 trades. Most trading activity at ZSPH appears discretionary, meaning executives are making active decisions rather than following pre-set schedules. This can make insider signals more meaningful for analysis.

Question 9
