Theta quantifies how much value is lost on the option due to the passing of time, known as time decay. Theta is typically negative for purchased calls and puts, and positive for sold calls and puts. If XYZ were trading at $50, and a 50 strike call with 150 days until expiration had...

because it changes the differential equations which govern the tissue. So, I have a WhenEvent set up for each edge within the tissue, to track if it becomes short enough for the cells to exchange neighbors. Then, when such an event occurs, the code stops the NDSolve block, runs the nei...
We modified MCAN and LXMERT2 in PyTorch to support training with multiple datasets and various adaptation strategies. We trained all models for 100K steps with batch size 128 (20 epochs on source). We chose AdamW (w/ weight decay) as optimizer, and used linear schedule war...
We want to test to ensure that the RMSNorm is doing what we think it should. We can do this the old-fashioned way: row-wise comparisons. The RMSNorm has the property where the norm of the layer will be the square root of the number of elements in the layer, so we can check that...
Beta decay of ^61_26Fe Show that the function y(x,t) = X^2+V^2t^2 is a solution of the general wave equation. Evaluate \int y0k \sin (kx-\pi)dx where y and k are independent of x, and y is given by the solution to the equation \cos(ky)=0.15 . ...
Moderate bear; Credit spread-Bear call spread. Use OTM strikes to take advantage of time decay. ITM is most directional. As a beginner I focus on two types of market stages: trend/directional and consolidation phases. My next endeavor is to study neutral strategies to take advantage of time...
Theta (θ) is a measure of the sensitivity of the option price relative to the option’s time to maturity. If the option’s time to maturity decreases by one day, the option’s price will change by the theta amount. The Theta option Greek is also referred to as time decay. ...
Time decay is also called theta and is known as one of theoptions Greeks. Other Greeks include delta, gamma, vega, and rho, and these formulas help you assess the risks inherent with an options trade. Special Considerations To understand howtime decay impacts an option, we must first review...
During the final hours before expiration, even though theta decay continues to increase, the relative influence from the underlying security’s price action begins to increase. Even a normal-sized move in the final hours before expiration can have a large impact on the change of the price–poten...
