The Poor Man’s Covered Call: How to Run a Covered Call With a LEAPS Diagonal for Less Capital

7 November 2026 , Abe Cofnas

A poor man’s covered call (PMCC) is an options strategy that mimics a covered call without owning 100 shares. It buys a deep in-the-money, long-dated call, often a LEAPS, and sells a near-term out-of-the-money call against it. Technically, it is a long call diagonal debit spread, a bullish position that needs far less capital. It […]

Cost-Push Inflation Explained: Causes, Real Examples, How It Differs from Demand-Pull, and Why It Drives Stagflation

6 November 2026 , Abe Cofnas

Cost-push inflation is a rise in the general price level caused by higher production costs rather than stronger demand. When energy, raw materials, wages, imported inputs or taxes cost more, firms raise prices to protect their margins. Because the pressure starts on the supply side of the economy, prices tend to rise while output falls. […]

Interest Rate Parity Explained: Covered and Uncovered IRP, Forward Rates, and Why the Carry Trade Still Works

5 November 2026 , Abe Cofnas

Interest rate parity is the no-arbitrage condition that links two currencies’ interest rates to their spot and forward exchange rates. The higher-yielding currency trades at a forward discount just large enough to cancel its yield advantage. Once the exchange rate is locked in, neither deposit earns more. The Fed lifted the federal funds rate to […]

The Diagonal Spread: How It Combines a Calendar and a Vertical Spread, Its Payoff, and the Poor Man’s Covered Call

4 November 2026 , Abe Cofnas

A diagonal spread is an options strategy that pairs two calls or two puts with different strike prices and different expiration dates. It combines a calendar spread with a vertical spread. Usually you buy the longer-dated option and sell the shorter-dated one, which adds a directional lean to a time-decay trade. It matters now because […]

Impermanent Loss Explained: Why Liquidity Providers Can Lose Value, the Math Behind It, and How to Reduce It

3 November 2026 , Abe Cofnas

Impermanent loss is what a liquidity provider loses against simply holding the same tokens when the price ratio of a pool’s two tokens changes. It is measured before fees. It is called impermanent because it shrinks if prices return to where they started, and it only becomes real when you withdraw. It matters now because […]

The Wage-Price Spiral: How Wages and Prices Feed Inflation, Why It Is Rarer Than It Sounds, and What It Means for Markets

2 November 2026 , Abe Cofnas

A wage-price spiral is a self-reinforcing loop between pay and prices. Rising prices push workers to demand higher pay, and higher pay pushes firms to raise prices again. Each round feeds the next, so inflation can outlast the shock that started it. Economists treat it as a form of cost-push inflation. US inflation was 3.7% […]

1 November 2026 , Abe Cofnas

A calendar spread is an options strategy that sells a near-term option and buys a longer-dated option at the same strike price. Both legs are calls or both are puts. It is also called a time spread or horizontal spread. It profits mainly from time decay, because the near-term option loses value faster than the […]

The Protective Put Strategy: How to Insure a Stock Position, What It Costs, and When to Use It

22 October 2026 , Abe Cofnas

A protective put is an options strategy in which you buy a put option on a stock you already own. The put gives you the right to sell at its strike price, so the strike becomes a floor under the position. You keep the upside and pay a premium for the cover. With stocks near […]
