Financial Securities, Portfolio, and Risk Modeling
The size of an investment portfolio is an important parameter to optimize in order to maximize returns. This example implements a venture capital portfolio model, to calculate the distribution of investment returns for a portfolio of 150 investments.
The original formulation of the model uses Monte Carlo simulations to calculate the distribution of investment returns, assuming that the portfolio’s individual investment returns each follow a Pareto distribution (i.e., a power-law distribution). When running on the Signaloid Cloud Compute Engine (SCCE), the kernels implementing the calculation can replace the usual approach of sampling followed by application of the kernel to the sample inputs, replacing it with a direct computation on a representation of the probability distribution of the portfolio model’s parameters. Thus, in a single computation, the code kernel running on SCCE can compute the same type of output distribution that would take a Monte Carlo simulation millions of iterations.
The investment portfolio kernel running on the Signaloid Cloud Compute Engine with a single-threaded Signaloid C0Pro-XL core achieves runtimes 125x faster than an optimized C-language Monte-Carlo-based implementation of the same kernel running on an Amazon EC2 R7iz instance. With 95% confidence, a 17M-iteration Monte Carlo implementation will have the same accuracy as the Signaloid UxHw®-based version, yet the Signaloid UxHw-based version gives the speedup quoted above; if requiring higher confidence in the accuracy of the Monte Carlo compared to UxHw, the speedups of UxHw are even greater.
The underlying distribution representations are not literal histograms: The distribution plots use an adaptive algorithm to render a mutually-consistent and human-interpretable depiction for both the Signaloid distribution representations and the Monte Carlo samples, to permit qualitative comparison.

Benchmarking Methodology
Monte Carlo simulations work by statistical sampling and therefore each multi-iteration Monte Carlo run will result in a slightly different output distribution. By contrast, Signaloid's platform is deterministic and each run produces the same distribution for a given Signaloid C0 core type.
The performance improvements are calculated by comparing Signaloid's platform with a Monte Carlo simulation of a similar quality of distribution. First, we run a large Monte Carlo simulation (about 50M iterations) on an AWS r7iz high-performance AWS instance: We use this distribution result as a baseline or ground truth reference of distribution quality. Then we calculate the performance of Signaloid's technology, and compare it with the performance of a Monte Carlo iteration count where the output distribution's Wasserstein distance (to the output distribution of the ground truth reference) is as accurate as the Signaloid-core-executed algorithm's output distribution, with 95% confidence level.
