iPath Series B Carbon ETN (GRN)

30.00 USD -0.27 (-0.879%) ⇩ (April 20, 2026, 11:54 a.m. EDT)

Short-term: ★★★☆☆ | Long-term: ★☆☆☆☆ | Dividends: ☆☆☆☆☆
Hot Take | April 18, 2026, 10:27 p.m. EDT

Avoid this security. Despite trading near its 52-week low with seemingly cheap 'book' value, GRN is a synthetic ETN with no dividend history and lacks the fundamental growth trajectory of the carbon sector it tracks. The recent price action is choppy and unimpressive, bouncing between dead.Flat technicals and zero speculative ammonia.

As of April 18, 2026, 10:27 p.m. EDT: Options liquidity is extremely sparse, limiting the reliability of standard positioning signals. However, the available data for the April 17 (weekly) expiry shows a distinct skew: significant Put Open Interest (OI) and volume at strikes of 31, 33, and 34, while Call OI is virtually non-existent outside of a single ATM anchor. Put IV is compressed but present (3.38% vs 4.51% for calls), suggesting traders are pricing in downside protection for near-term events. The general lack of call positioning aside from the anchor suggests a defensive stance or lack of aggressive bullish speculation in this low-cap environment.
