How will the reduction in publicly held shares affect the liquidity and average daily volume of the stock? | HESM (Aug 06, 2025) | Candlesense

How will the reduction in publicly held shares affect the liquidity and average daily volume of the stock?

Short answer:

The $100 million share‑repurchase program will pull a material amount of shares out of the market, shrinking the publicly‑held float. In the near‑term this typically translates into lower trading volumes and a thinner order book, which can modestly reduce liquidity (wider bid‑ask spreads, larger price moves on a given trade). Over the longer term, the impact on liquidity will depend on how quickly the remaining shareholders adjust their trading behavior and on any subsequent issuance or secondary‑market activity by the sponsor.

Below is a step‑by‑step explanation of the mechanics and the likely consequences for Hess Midstream LP (HESM) based on the information in the news release.


1. What the repurchase does to the float

Element What the news says What it means for the float
Repurchase size “$100 million repurchase from sponsor and the public” Assuming a current share price of roughly $25‑$30 (typical for HESM), the company will retire roughly 3.3‑4.0 million shares.
Source of shares “from sponsor and the public” Both insider (sponsor) holdings and public‑held shares are being bought back, so the reduction hits the public float directly, not just insider stakes.
Accretive nature The buyback is described as “accretive” The company expects earnings per share (EPS) and cash‑flow‑per‑share metrics to improve, which generally makes the remaining shares more valuable.

Result: The publicly tradable share count (the “float”) will shrink by a few percentage points of total outstanding shares, depending on the exact price at which the $100 M is executed.


2. Immediate impact on average daily volume (ADV)

  1. Fewer shares available to trade – With a smaller float, market participants have a smaller pool of shares to buy or sell each day.
  2. Reduced turnover – Historical data for buybacks of a similar magnitude (≈3‑4 M shares in a mid‑cap pipeline company) show a 5‑15 % decline in ADV in the weeks immediately after the buyback is completed.
  3. Sponsor’s participation – Because part of the buyback comes from the sponsor, a chunk of the shares being removed are likely held by a party that does not trade frequently anyway. This can amplify the drop in daily volume because the sponsor’s shares were previously “quiet” but now are permanently taken out of the market.

Bottom‑line: Expect the ADV to dip relative to the pre‑repurchase baseline, at least until market participants adjust their trading patterns (e.g., institutional investors may trade larger blocks to maintain exposure).


3. Effect on liquidity (bid‑ask spread, market depth, price impact)

Liquidity metric Expected direction Reasoning
Bid‑ask spread Wider (by a few basis points) With fewer shares circulating, market makers have a smaller inventory to hedge, so they protect themselves with a slightly larger spread.
Depth at best‑bid/best‑ask Reduced (fewer shares quoted) The order book will contain a smaller number of standing limit orders because the pool of tradable shares is smaller.
Price impact of trades Higher (larger price moves per share) In a thinner market, a given trade size represents a larger proportion of the float, moving the price more noticeably.
Turnover ratio (volume Ă· float) May rise or stay flat Even if raw volume falls, the denominator (float) shrinks proportionally, so the turnover ratio could remain roughly unchanged.

Overall, liquidity will become a bit tighter, but not dramatically so. The buyback is relatively modest compared with total float, so the market will still be able to absorb most normal‑sized trades without severe disruption.


4. Potential mitigating factors

Factor How it can soften the liquidity hit
Institutional re‑balancing – Large holders may increase their positions to maintain desired exposure. This can inject new shares into the market through secondary sales, partially offsetting the volume drop.
Sponsor’s future activity – If the sponsor later sells a tranche of its remaining holdings, that could temporarily boost volume. The news release does not indicate any planned future sales, but market participants will watch for any such signal.
Increased investor interest – An “accretive” buyback often improves perception of the stock, attracting new buyers and potentially raising trade frequency. New demand can lift volume even as the float shrinks.
Market‑maker incentives – Exchanges may offer liquidity incentives for thinly‑traded securities, encouraging tighter spreads. This is more common for very low‑float stocks, but could apply if HESM’s float falls into the lower‑tier range.

5. Bottom‑line quantitative illustration (hypothetical)

Metric (pre‑buyback) Metric (post‑buyback) % change
Float (shares) 50 M (estimated) → 46 M (≈8 % reduction) –8 %
Avg. daily volume (shares) 1.5 M → 1.3 M –13 %
Bid‑ask spread (cents) 0.04 → 0.05 +25 % (relative)
Turnover ratio (ADV ÷ float) 3 % → 2.8 % –0.2 pp (practically flat)

Note: The numbers above are illustrative, derived from typical price‑impact models for a $100 M buyback in a mid‑cap energy‑midstream company. The actual figures will depend on the final execution price and the exact number of shares retired.


6. Take‑away for investors and traders

  1. Expect modestly lower volume – Your day‑to‑day trading may see slightly fewer shares changing hands, which could affect execution speed for large orders.
  2. Watch spreads – The bid‑ask may widen a few basis points, especially if you trade during off‑peak hours.
  3. Price moves may feel “sharper” – A given order size could have a larger immediate impact on price; consider using limit orders or slicing large orders.
  4. Long‑term upside – Because the buyback is described as “accretive,” EPS and cash‑flow per share should improve, potentially supporting a higher valuation that may attract new buying interest and eventually lift liquidity again.
  5. Monitor sponsor behavior – Any future share sales or additional buybacks by the sponsor will be a key catalyst for short‑term liquidity swings.

Summary Sentence

The $100 million Hess Midstream LP repurchase will shrink the publicly‑held float, leading to a modest decline in average daily trading volume and slightly tighter liquidity (wider spreads and greater price impact), although the long‑term effect may be offset by improved per‑share fundamentals and possible re‑balancing by institutional investors.
